Distinguish the Dashboard and Plan age-4 figures

Both screens showed an "expiring at age 4" number under near-identical
labels, and they disagreed -- 143 on the Dashboard versus 100 on the Plan
tab for the same parent. Both were correct: the Dashboard reflects the
saved plan, the Plan tab a proposal that has not been applied and which
simulates future recurring wishes.

The numbers are left untouched; forcing them to agree would make one of
them wrong. Instead each label now states its own basis ("om nuvarande
plan följs" / "om detta förslag tillämpas"), and the Plan tab's intro
says outright that the saved plan may differ, and why.

Tests assert the distinguishing copy on both screens so the two cannot
silently drift back to indistinguishable labels.
